Glacier Rock Dust

Question: One of the customers at our shop has asked about glacier rock dust. I found only one source, and it is in the United Kingdom. Do you know anything about this product? Is it something we should try to get, or do more readily available products fill the bill? M.M., Athens

Answer: Because glacier rock dust is loaded with trace minerals, it's probably beneficial for the soil. The only question is the cost vs. that of lava sand, granite, green sand, etc. I know of no other sources
